Natural History Of The Marbled Salamander, Ambystoma Opacum (Gravenhorst), In West Virginia, With Special Notes On Reproduction And Larval Development, Jason J. Watkins Jan 1999

Natural History Of The Marbled Salamander, Ambystoma Opacum (Gravenhorst), In West Virginia, With Special Notes On Reproduction And Larval Development, Jason J. Watkins

Theses, Dissertations and Capstones

This study observed a population of Ambystoma opacum in Kanawha State Forest, Kanawha County, five miles south of Charleston, West Virginia. Data were collected from September 1995 to November 1997. Reproductive biology and salamander development were examined. Predation of A. opacum and potential predators were also noted. Like other species in the genus Ambystoma, adult A. opacum are mostly fossorial and rarely seen above ground outside of the breeding season. During the breeding season, adults make their way to the breeding pools. Males ventured to the breeding pool first in early September and ranged in size from 49 to 75mm …


The Relationship Between Ohio River Bass Tournament Success Rates, Forage Fish Abundance And Environmental Conditions, Jeffrey V. Ginger Jan 1999

The Relationship Between Ohio River Bass Tournament Success Rates, Forage Fish Abundance And Environmental Conditions, Jeffrey V. Ginger

Theses, Dissertations and Capstones

Due to increasing pressure from Ohio River bass anglers with regard to decreasing catch rates in 1981,1990, and 1997, the West Virginia Division of Natural Resources (WVDNR) initiated a study of black bass populations. The Ohio River Valley Water Sanitation Commission (ORSANCO), in conjunction with state and Federal agencies, has collected population data on Ohio River fishes at lock chambers and has measured various water quality parameters since 1957. That data coupled with Ohio River bass tournament data collected by the DNR since 1975 and other fishery data sets provided a historic look into the variability of angler success. These …


Food Habits Of Salmo Trutta And Salvelinus Fontinalis (Pisces: Salmonidae) In Relation To Seasonal Changes And Mitigative Liming Effects In Dogway Fork Of The Cranberry River, West Virginia., Jason A. Morgan Jan 1999

Food Habits Of Salmo Trutta And Salvelinus Fontinalis (Pisces: Salmonidae) In Relation To Seasonal Changes And Mitigative Liming Effects In Dogway Fork Of The Cranberry River, West Virginia., Jason A. Morgan

Theses, Dissertations and Capstones

Dogway Fork, a tributary of the Cranberry River in West Virginia, is acidic due to acid precipitation and poorly buffered soils. This study is part of a long-term investigation involving the effects of continuous limestone neutralization on the fishes and benthos of an acid stream. Prior to treatment in 1988, the stream had a pH of 4.5 and there were no fish present. Since treatment began, the pH of the stream has risen to 6.8. Nine species of fish have been collected and six species have reproduced following the improvement in water quality. Densities of specific acid-sensitive benthic macroinvertebrates have …


Interaction Of Laminin Beta2 With Eps8 And Desmin In Muscle Cells, Luke Xueliang Cui Jan 1999

Interaction Of Laminin Beta2 With Eps8 And Desmin In Muscle Cells, Luke Xueliang Cui

Theses, Dissertations and Capstones

Laminin β2 is localized to the synaptic basal lamina (BL) in muscle and glomerular BL in kidney. To find interacting proteins, a mouse kidney cDNA library was screened with domain I of rat laminin β2 using the yeast two-hybrid system. Fifteen positive clones were found. The DNA sequence of three each of these clones corresponded to the phosphoprotein Eps8 (epidermal growth factor receptor pathway substrate clone 8, which is tyrosine phosphorylated after EGF stimulation) and the intermediate filament (IF) protein keratin. To determine if this interaction occurred in muscle cells, C2 cells transfected with the rat …


Natural History Of The Northern Spring Salamander Gyrinophilus Porphyriticus Porphyriticus At The Westvaco Wildlife And Ecosystem Research Forest In Randolph County, West Virginia, Brian A. Lindley Jan 1999

Natural History Of The Northern Spring Salamander Gyrinophilus Porphyriticus Porphyriticus At The Westvaco Wildlife And Ecosystem Research Forest In Randolph County, West Virginia, Brian A. Lindley

Theses, Dissertations and Capstones

The purpose of this thesis research was to study the natural history of the northern spring salamander Gyrinophilus p. porphyriticus in West Virginia. The objectives of this study were to determine the environmental characteristics of the habitat of Gyrinophilus p. porphyriticus, to determine its reproductive biology, and then examine non-reproductive aspects of the natural history of the species. Study sites were located at the Westvaco Wildlife and Ecosystem Research Forest (WWERF) in Randolph County, West Virginia. Four sites on three streams were divided into two 25m transects. All sites were examined once each month from August 1997 through November 1998 …
